Interesting paper on his improved replication, with a glaring error: https://drive.google.com/file/d/0B5Pc25a4cOM2cHBha0RLbUo5ZVU/view Their conclusion is flat-out wrong: "After operation in the reactor, No significant changes in the isotopic composition of Ni was found. Li 6/ 7 Li ratio increased."
In fact the Lithium ratio is in the noise, given the mobility of lithium - BUT a very substantial change in 64Ni can account for all of the excess heat. This is evidence that they enriched in 64Ni and knew it was the key - not 62Ni and no lithium.
